FIELD OF THE INVENTION

The invention relates generally to the filed of photography, and inparticular to electronic photography. More specifically, the inventionrelates to a digital camera that interfaces with a host computer.

BACKGROUND OF THE INVENTION

Digital cameras, such as the Kodak Digital Science DC25™ camera, allowimages to be utilized on a home computer (PC) and to be incorporatedinto e-mail documents and personal home pages on the World Wide Web.Presently, images must be copied to the PC and transmitted as e-mail,for example using an online service or an Internet Service Provider(ISP), via a modem from the user's PC. It would be desirable to be ableto transmit pictures directly from the digital camera instead of firsttransferring the pictures to a PC. For instance, on a vacation trip, itis desirable to immediately share pictures with friends or relatives viae-mail or Internet access. It is also desirable to transmit picturesfrom a location without PC access in order to free up camera storage totake additional pictures. There are a wide variety of connection meansto online services such as America On Line, ISPs, and bulletin boardservices. Each of these services typically requires an account name andpassword, as well as local telephone access numbers, and specificcommunications settings. It would be difficult to provide an easy-to suemeans with buttons or menus on a small digital camera to input and/ormodify all of these required settings.

SUMMARY OF THE INVENTION

The present invention is directed to overcoming one or more of theproblems set forth above. Briefly summarized, according to one aspect ofthe present invention, the invention resides in a digital camera forcapturing a plurality of images comprising an image sensor for receivingincident light of a scene, the digital camera capturing an imagecorresponding to the incident light of the scene; a display fordisplaying the plurality of captured images and for displaying a menu ofdestinations; at least one user input for selection of at least oneimage from the plurality of captured images and a destination from themenu of destinations displayed on the display; a communicationsinterface for transmitting the at least one selected image to theselected destination over one of a plurality of networks, the pluralityof networks including at least two different types of wireless networks;a memory; and a processor coupled to the image sensor, the display, theat least one user input, the communications interface, and the memory,the processor controlling the transmission of the at least one selectedimage to the selected destination using either one of the at least twodifferent types of wireless networks.

These and other aspects, objects, features and advantages of the presentinvention will be more clearly understood and appreciated from a reviewof the following detailed description of the preferred embodiment andappended claims, and by reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Because imaging systems and devices are well known, the presentdescription will be directed in particular to elements forming part of,or cooperating more directly with, apparatus in accordance with thepresent invention. Elements not specifically shown or described hereinmay be selected from those known in the art. Some aspects of the presentdescription may be implemented in software. Unless otherwise specified,all software implementation is conventional and within the ordinaryskill I the programming arts.

A system block diagram of the invention is shown in FIG. 1 including anelectronic still camera 10, a host computer (PC) 12 and a serviceprovider 14. The camera includes an optical section 20 for imaging ascene upon a CCD sensor 22 and generating an image signal, a liquidcrystal display (LCD) 24 for displaying images and other information, anumber of user input buttons 26, both permanent memory 28 and removablememory 30, and an internal communications interface (32) (e.g., modem).This interface may connect to a variety of known networks, such as apublic switched telephone network (PSTN), ISDN, an RF cellular phonenetwork, or Ethernet. The camera 10 also includes a microprocessor 34for generally controlling the camera functions, as well as theinterchange of data with the host PC 12 and the memory card 30 through ahost PC interface 36 and a memory card interface 38, respectively.Besides the host PC 12, the system includes a network connection 40 tothe online service or ISP (Internet Service Provider) 14. Alternately,the network 40 can connect to the user's home PC 12.

When the camera 10 is first purchased (or at any time thereafter), it isconnected to the PC 12 via the host PC 36 interface and a softwareapplication (stored on a disc 45) running on the host PC 12 will enablethe user to specify the name of a destination ISP or online service andto input from the host PC keyboard 44 the appropriate communicationsettings and account information. This information generates a networkconfiguration file, which then can then be downloaded to the camera 10through the host PC interface 36, which may be a wired or infrared(e.g., IrDA) interface, and written to the camera's internal memory 28and/or the removable memory card 30. Alternatively, a host PC equippedwith a memory card reader/writer 42 can write the information directlyto the card 30 without connecting the camera through its host PCinterface 36. Also, this information could be predetermined by the userand stored in a “preferences” file on the host PC 12 and thentransferred to the camera 10 from this file without further interventionby the user. Multiple sets of destination services can be stored on thememory card 30. Typically, keyword or graphic descriptors (e.g., icons)accompany the information in the network configuration file aboutdestination services to enable easy access by the camera user.

The steps used to automatically transmit images using the networkconfiguration file are shown in FIG. 2. After disconnecting the camerafrom the host PC, the user operates the camera to take pictures (step50). This is typically done at a remote location, for example whiletraveling to another city. As the user takes or reviews images on theimage LCD display, the decision can be made to transmit one or moreimages (step 52). This is done by choosing one of the keywords or iconsin a menu 54 shown in FIG. 2, which are displayed on the LCD 24 andselected, e.g., through the user buttons 26. (Note that a camera willtypically only include a subset (only those desired by the user) of allthe different services shown.) The selected image files may be taggedwith a code (step 56) indicating which service is requested, as shown inFIG. 3. (Alternately, an “image utilization” file can be created in thecamera storing a list of images to be transmitted by a particularmethod, as described in the cross-referenced copending patentapplication (U.S. Ser. No. 60/037,963). As described in that patentapplication, the details of an order, e.g., number of print copies to bemade from an image and the size of the prints and/or a list of images tobe e-mailed to various recipients, is written into the “utilization”file, which identifies the order and includes pointers to the imagefiles that store the images required to “fulfill” the order. The“utilization” file is stored in the internal memory 28 or the memorycard 30.)

Next, the system determines whether a request exists to send an image(step 58). If no request is present, the image and associated data isstored in either permanent memory 28 or the memory card 30 (step 59).(Typically, all images are initially saved in memory whether eventuallysent or not.) Otherwise, if there is a request to send an image, theuser ensures that the camera is connected to the appropriate service(wired telephone line, cellular phone, kiosk, etc.) and pushes a “send”button in the user button section 26, or selects a “send” menu option onthe LCD 24. The camera then utilizes the appropriate networkconfiguration file, shown in FIG. 4. Each network configuration filecontains items such as the protocol type, phone number, etc., asdescribed in Appendix I. The user password may be checked against thepassword in the network configuration file to ensure that the user isauthorized to connect the camera to the desired service (step 60).Alternately, the stored password in the appropriate configuration filecan be used. Next, the camera uses the parameters in the configurationfile to establish communications with the service and send one or moreimage files as selected by the user (steps 62). The service receiverinterprets the system commands issued by the camera from the networkconfiguration file list and sends appropriate feedback (such as“transfer in progress” and “transfer complete”) which are interpreted bythe camera and displayed on the LCD 24 (steps 64).

For example, when the camera uses a normal wired telephone (PublicSwitched Telephone Network) connection (i.e., network 40) to thecamera's internal modem 32, after the user selects the images to be sentand presses the “send” button, the camera performs the following stepswithout user intervention:

-   1) Read the appropriate connection parameters from the network    configuration file (on the memory card 30 or internal camera memory    28), dial the phone and establish the connection to the destination    service 14.-   2) Read the user's account name and password and transmit these to    “log-on” to the service 14.-   3) Using the appropriate communications protocol (FTP, mailto,    etc.), transmit the selected image or images to the destination    service 14.

The invention has been described with reference to a preferredembodiment. However, it will be appreciated that variation andmodifications can be effected by a person of ordinary skill in the artwithout departing from the scope of the invention.

APPENDIX I

These are descriptions of the tags listed in the previous drawing:

Protocol Type

Each communication method has its own protocol, or rules to communicate.This tag identifies that protocol and where to find it. For example, theNetwork may use TCP/IP and a modem may use XModem.

Phone Number

This is the number of the receiving service. If internet access isrequested, this could be the number of the Internet Service Provider.For ISDN, some systems require two phone numbers, dialed and connectedto in sequence.

Default Settings

Standard settings that make the communications device compatible withthe imaging device.

Modem Control String

Modem and communications devices have a command language that can setthem up before they are used. For example, modems have many optionscontrolled by command strings including volume level, the amount of timethe carrier is allowed to fail before the system hangs up, and so on.

Account Data

This can be internet account data, charge number data, phone card data,billing address, and data related to the commerce part of thetransmission.

Password

Any password needed to get into the communications system. Otherpasswords to get into the remote application or destination are locatedin the System Commands section.

System Commands

These are commands that control the end destination.

Error Protocol

In cellular and some other wireless communications, error protocols areused to increase the robustness of the link. For example, MNP10 or ETCmay be used for cellular links.

Radio Type

The type of radio used for this communications feature may be identifiedhere. Some cell phones have modems built in, others will have protocolsfor many communications functions built in. The radio type will make theimaging device adapt to the correct interface.

IOC

ISDN Ordering Code identifies what features are available on the ISDNline provided by the teleco. It is used to establish the feature set forthat communications link.

Internet Service Provider

This identifies the actual service provider and any specific informationor sequence of information that the service wants to see duringconnection and logoff. It also tells the device how to handle the returnmessages, like “time used” that are returned by the server.

Commands to Receiver

This may be a list of commands to control the receiving application. Forexample, a command to print one of the images and save the data to aparticular file on a PC may be embedded here.

Return Status Requests

This tag can set up the ability of the application to tell if an errorhas occurred, or what the status of the application might be. The datahere will help the device decide if it should continue communicating anda set user interface response can be developed around this feedback.
